Reaction Steps

4H,6H-1,2,5,10b-Tetraaza-benzo[e]azulene-5-carboxylic acid tert-butyl ester was deprotected using trifluoroacetic acid and the resulting salt was coupled with (R)-3-[(tert-butoxycarbonyl)amino]-4-(2,4,5-trifluorophenyl)butanoic acid using HOBt, EDC and DIPEA. The desired compound was obtained as viscous oil.
